BINDER.

Specification of Letters Patent.

Patented May 23, 1916.

Application filed May 11, 1914. Serial No. 837,898.

To all wiwmc't may concern:

Be it known that I, GEORGE H. JENKINS,

a citizen of the United States, residing at Oak Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Binders, of which the following is a specification.

This invention relates to binders within which leavesmay be temporarilyor permanently bound, and has reference to certain peculiarities ofconstruction by which a permanent binding may be effected, the temporarybinding means cooperating for this purpose.

In this invention, I have sought by very simple arrangements to providea binder,

the covers of which are utilized in the ordinary manner,;but which arecapable of further use in cooperating to effect a permanent binding ofthe leaves therein while still retained within the covers; and toaccomplish the above end without adding materially to the cost ofmanufacture or size of the binder. 7

The invention further consists in numerous other features ofconstruction and combinations of parts as will more fully hereinafterappear.

In the drawing: Figure 1 is a perspective View, showing the covers ofthe present binder in operative position; Fig. 2 is a side elevation ofthe same, showing a number of leaves arranged in position; Fig. 3 is asection on line 3-3 of Fig. 2; Fig. 4 is a side elevation of the leavesas permanently bound; Fig. 5 is a detail of the end of one ofthe covers,exhibiting a modification of the construction shown in Figs. 1 and 3;and Fig. 6 is a detail of a further modification of cover construction.

In the embodiment of my invention, two binder covers are utilized,between which a stack of leaves are bound through the instrumentality ofposts, thongs, straps, or any other suitable means. The binder covers,for present purposes, may be considered as temporary, in that they areused only until their binding capacity has been reached, after which atransfer of their contents to permanent covers is made. In thetransferring of the leaves to the permanent covers and binding ofsame'therein, the temporary covers are not at first removed, but areused to assist in this operation.

Referring to the drawing, I have shown two covers 8 and 9 for currentleaves, the

means for securing the same between the covers comprising posts 10threaded to receiveeach a thumb nut 11. As is usual in covers of thiskind, the end binding portion 12 is joined to the body 13 thereof by aflexible connection 14 to permit of ease in manipulation and facility inhandling.

The end portions 12 in the present device are each reinforced-by asuitable plate, to which the posts or other connecting means aresecured, and in which a plurality of openings 15 are arranged, theseopenings being interconnected by slots 16 of a width less than thediameter of said openings. It is intended that the openings and slots inthe end binding portions of each cover shall be located in registeringpositions. The slot and enlarged opening arrangement may be modifiedwithout, however, departing from the underlying principles of thisinvention. Instead of this precise construction, a single continuous andwidened slot may extend between the outermost openings 15 in either orboth of the covers.

During use, it is contemplated that one of the covers 17 (which, forpurposes of differentiation, will be termed a permanent cover) shall beinserted adjacent the inner side of one of the binder covers. The leavesare added from time to time, as required,

and are secured in position upon the posts,

the invention illustrated, this end is accomplished by screwing down thethumb nuts 11 against the reinforced end binding portions, so that thebound edges of the leaves are compressed and firmly held. If the leavesbetween the covers are, previous to insertion, punched with holesadapted to register with the openings 15 in' the end portions of thecovers, no punching or drill ing operation is required at this time. Ifotherwise, however, the binder, together with the leaves, is broughtinto operative position with a punch. for this purpose, or suitabledrills are employed, to provide openings through othefleaves inalinement with the openings 15. Cords or other suit able tying devicesare then strung'throughf the ope'nings and alining holes in the paper tosecure the same in permanent bound form. Inasmuch as the end portions 12are tightly compressed upon the edges of the paper to be' bound, noappreciable amount of labor is required for this operation. It

is obvious, as the cords are strung throughto their permanent position,that they will lie tightly against. the permanent covers, passingthrough the temporary covers to such position through the'slots 16. Theop- V eration having be'encarriedout in the manner described, thetemporary covers are removed, to be again available for'use, While theleaves theretofore bound between such covers are permanently bound as anindependent book.

It 1s contemplatedthat to the permanent cover which :lies" adjacent thetemporary cover at thetime the leaves were first placed" on file, aflexible backing 18 should be attached which is folded back out. of theway prior to use in the manner indicatedin Fig.

'2. 'When the binding operation has been completed, this backing iscarried around and secured in position across thezback of the permanentcovers, as appears in Fig. 4:.

In this manner, the cords extending across the end portions ofthepermanent covers are concealed and protected, and asurface is providedonthe back of the file to which labels' or other marks may be attached.

Although the binder illustrated in Fig. 1

.sho'ws but two posts andthree openings between the same, it is obviousthat the num ber ofposts or openings maybe varied to suit specialrequirement oi use. In Fig. 5, for: instance, an end portion havingthree posts is shown, between each two of which openings 15, 16 areprovided through which a cord may be, strung for binding purposes.
